COMBINED DRlLLlNG-TOOL AND SAND- BAILER.

SPECIFICATION forming part of Letters Patent No. {178,605, dated July12, 1892.

Application filed September 28, 1891. Serial No. 407,059. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS N. IRELAND, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and usef ul Improvementsin aCombined Drilling-Tool and Sand-Bailer; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to an improved combined drilling-bit andsand-bailer; and it consists in certain details of construction andcombination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a sectional side elevation ofmy improved drilling-bit and bailer, which is constructed in accordancewith my invention. Fig; 2 is an edge elevation of the bit, showing thesemispherical portion which forms a valve-seat for the bailer. Fig. 3 isa side sectional elevation of my improved apparatus, in which aremovable bit is shown, together with a sliding sleeve for dischargingthe contents of the bailer.

To put my invention into practice, I provide a bar 1 of a suitablelength and form on the upper end a means 2 for connecting the same tothe jars of drilling-tools such as are now in common use. This bar orstem 1 is enlarged at the lower end to form a bit 3 and a semi-sphericalportion 4, formed above the same,which serves as a seat for the lowerperiphery of a tube 5, which incloses or surrounds the stem 1. This tube5, which extends from a short distance above the bit to a point near thetop of the stem and held centrally about the said stem by an enlargement6, formed at the base of the tube 5,'is an opening 8, covered with asleeve 9, capable of be ing elevated to uncover the said opening 8 todischarge the contents of the bailer. A removable bit1O-sucl1 as shownat Fig. 3may be used, if desired.

In operation the downward vertical movement given to the tools lifts thetube 5 and works the sand into the intervening space 7 between the stem1 and the tube 5, and at the upward movement of the tool the tube closeson its seat and retains the sand within the same. After the drillingoperation has been continued for some time the apparatus is drawn fromthe well and the sand removed from the same by elevating the tube fromits seat, or the sleeve 9, covering the opening 8 in the base of thetube 5, may be used to remove the contents of the bailer.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The herein-described combined drilling-tool and sand-bailer, comprisingthe rod or stem 1, having near its top the enlargement 6 and at itsbottom a drilling-bit, said drilling-bit having an enlarged head, a tube5, encircling said rod or stem'and movable automatically, as described,said tube being of less diameter than said bit-head and adapted to seatitself thereon when the same is raised, guided by said enlargement 6 andformed near its bottom with an opening 8, and means for closing saidopening.

In testimony that I claim the foregoing I hereunto affix my signaturethis 30th day of July, A. D. 1891.

In presence of Ms. J MCAFEE, M. E. HARRISON.
